DETAILED DESCRIPTION

Reference will now be made in detail to embodiments of the present disclosure, examples of which are described herein and illustrated in the accompanying drawings. While the present disclosure will be described in conjunction with embodiments and/or examples, they do not limit the present disclosure to these embodiments and/or examples. On the contrary, the present disclosure covers alternatives, modifications, and equivalents.

In embodiments, such as generally illustrated in FIGS. 1A and 1B, a track system 100 may include a support assembly 102 and/or one or more track/rail assemblies 104. A support assembly 102 and/or a track assembly 104 may include and/or be connected to an electrical system (e.g., of a vehicle 108), which may include a controller and/or a power source.

In embodiments, such as generally illustrated in FIGS. 1A and 1B, a track assembly 104 may be connected to and/or disposed in a mounting surface 106 (e.g., a floor of a vehicle 108) and may facilitate selective connection of one or more support assemblies 102 to the mounting surface 106. A track assembly 104 may facilitate adjustment of one or more support assemblies 102, such as relative to the mounting surface 106 and/or within a vehicle 108. In examples, a track system 100 may include several track assemblies 104 that may be configured to engage a corresponding portion of a support assembly 102. Several track assemblies 104 may be connected to a portion of the mounting surface 106 (e.g., a floor, wall, ceiling, etc.), may extend parallel to one another, and/or may be offset from each other in a lateral/transverse direction (e.g., a Y-direction) such that the track assemblies 104 may be generally aligned with respective outer sides of a support assembly 102.

With embodiments, such as generally illustrated in FIGS. 1A-2, a track assembly 104 may include an outer track 120 and/or an inner track 150. An outer track 120 and/or an inner track 150 may be an elongated member extending generally in an X-direction (e.g., a longitudinal direction). An outer track 120 and/or an inner track 150 may facilitate movement and/or adjustment of a support assembly 102 and/or a support member 200 along a track assembly 104. For example and without limitation, a support member 200 may roll along a top surface of an outer track 120 via one or more rolling members 220, and/or a support member 200 may selectively engage the outer track 120 and/or the inner track 150 to selectively restrict/control relative movement between a support assembly 102 and a track assembly 104. An outer track 120 and/or an inner track 150 may include one or more of a variety of materials. For example and without limitation, the outer track 120 may include a first material (e.g., aluminum) that may be relatively light, and/or the inner track 150 may include a second material (e.g., steel) that may be relatively strong compared to the first material.

With embodiments, such as generally illustrated in FIG. 2, an outer track 120 may have a track base portion 122 and two track wall portions (e.g., a first track wall portion 124 and a second track wall portion 126) protruding from the track base portion 122 to form a generally U-shaped cross-section in a Y-Z plane (e.g., in a plane perpendicular to an X-direction). The U-shaped cross section may define a track receptacle 130 configured to receive and/or at least temporarily retain a portion of a support assembly 102. A first track lip/wing 132 and a second track lip/wing 134 may project inwardly toward one another from the first track wall portion 124 and the second track wall portion 126, respectively. A track opening 128 may be defined between the two track lips 132, 134. A portion of a support assembly 102 may be inserted into the track opening 128 and selectively retained within the track receptacle 130. An outer track 120 may include a first rolling portion 136 and/or a second rolling portion 138, which may be configured to engage one or more rolling members 220 of a support member 200. A first rolling portion 136 may be disposed on and/or adjacent to a first track lip 132 (e.g., at or about a top surface of the outer track 120). A second rolling portion 138 may be disposed on and/or adjacent to a second track lip 134. A first rolling portion 136 and/or the second rolling portion 138 may be configured as a ridge, for example, protruding from a track assembly 104 in a Z-direction and/or may extend substantially in an X-direction along some or all of a length of the outer track 120.

With embodiments, such as generally illustrated in FIGS. 2 and 3, an inner track 150 may be disposed partially and/or completely within a track receptacle 130. An inner track 150 may be disposed on and/or connected (e.g., fixed) to a track base portion 122 and/or one or more track wall portions 124, 126 of an outer track 120. An inner track 150 may, for example, include a generally L-shaped cross section. An inner track 150 may include a hook portion 152, which may be disposed adjacent to and/or extend adjacent to a first track wall portion 124 and/or a first track lip 132.

With embodiments, such as generally illustrated in FIGS. 2 and 3, a track assembly 104 may include one or more toothed portions 154 (e.g., gear racks) configured to engage an adjuster pinion 250 of an adjuster assembly 230. A toothed portion 154 may include one or more track teeth 156. A toothed portion 154 may generally extend in an X-direction, such as along all or a portion of a length of the inner track 150. One or more (e.g., all) of the track teeth 156 may be disposed one after another and/or aligned with one another in an X-direction. Track teeth 156 may extend and/or protrude from the toothed portion 154 generally in a Z-direction (e.g., downward in the Z-direction toward the mounting surface 106). A toothed portion 154 may be disposed within a track receptacle 130 and/or may be disposed on an underside of a track assembly 104. A toothed portion 154 may be connected to and/or formed as a portion of an outer track 120 and/or an inner track 150. For example and without limitation, a toothed portion 154 may be connected to and/or integrally formed with an inner track 150, such as at or about a distal end of a hook portion 152. A toothed portion 154 and/or track teeth 156 may be disposed adjacent to and/or substantially aligned/overlapping (e.g., in a Z-direction) with an edge of a first track lip 132 that at least partially defines a track opening 128.

In embodiments, such as generally illustrated in FIG. 2, a track assembly 104 may include one or more electrical conductors 160 (e.g., bus bars) configured to selectively contact and/or engage (e.g., electrically connect with) one or more contacts 212 of a support assembly 102. With examples, a conductor 160 may be an elongated member extending in the X-direction and/or may have a generally U-shaped cross section that opens in a Y-direction. A conductor 160 may be operatively connected to a controller and/or a power source. A conductor 160 may be connected to a first track wall portion 124 and/or a second track wall portion 126 of an outer track 120, and/or another portion of a track assembly 104. A conductor 160 may be connected to a track assembly 104 via an insulator 170, which may be configured to electrically insulate/isolate a conductor 160 from other portions of a track assembly 104. An insulator 170 may be an elongated body, which may extend in an X-direction, and/or may be configured to receive and/or retain one or more conductors 160.

With embodiments, such as generally illustrated in FIGS. 1A, 1B, 6, 7, and 10A-11, a support assembly 102 may include a support member 200. A support assembly 102 and/or a support member 200 may be adjusted and/or moved along a track assembly 104 (e.g., in an X-direction) manually and/or via an adjuster assembly 230. A support member 200 may be configured for connection with and removal (e.g., in a Z-direction) from a track assembly 104, such as in a plurality of locations along the track assembly 104. A support member 200 may, for example and without limitation, include, be connected to, and/or support a seat, such as a vehicle seat, and/or one or more other components (e.g., consoles, cargo, cargo racks, etc.). The support assembly 102, the support member 200, and/or one or more components connected thereto may include one or more electrical components (e.g., controllers, power sources, seat heaters, airbags, air bladders, fans, etc.). A support member 200 may be configured as a base, a leg, and/or a support structure, for example.

With embodiments, such as generally illustrated in FIGS. 1A, 1B, 6, 7, and 10A-11, a support member 200 may include one or more electrical connectors 210 that may be configured for selective connection with a track assembly 104. An electrical connector 210 may be configured to selectively electrically connect with a track assembly 104, such as with a conductor 160 (e.g., a bus bar) of the track assembly 104. For example, one or more contacts 212 of the electrical connector 210 may rotate into and out of contact with one or more conductors 160. Electrical connection between an electrical connector 210 and a conductor 160 may permit electrical power and/or one or more signals (e.g., control signals, sensor data signals, etc.) to be provided to and/or received from the support member 200 (e.g., an electrical component).

With embodiments, such as generally illustrated in FIGS. 1A, 1B, 6, 7, and 10A-11, a support member 200 may include one or more rolling members 220. A rolling member 220 may be configured to engage and/or roll along a first rolling portion 136 and/or a second rolling portion 138 of a track assembly 104. A support member 200 may be configured to move along a track assembly 104, at least in part, via one or more rolling members 220 (e.g., rolling members 220A, 220B). In embodiments, a rolling member 220 may be configured to support at least a portion of the support assembly 102. A rolling member 220 may rotate as the support assembly 102 moves along the track assembly 104. A rolling member 220 may be rotatably connected to a body of the support member 200. For example and without limitation, a first rolling member 220A may be rotatably connected at or about a first end of a support member 200, and/or a second rolling member 220B may be rotatably connected at or about a second end of the support member 200. One or more rolling members 220 (e.g., first and second rolling members 220A, 220B) may be connected to the same lateral side of a support member 200. In such embodiments, a first and second rolling member 220A, 220B may both engage and/or roll along the same rolling portion (e.g., a first rolling portion 136, a second rolling portion 138, etc.). Additionally and/or alternatively, rolling members 220 may be rotatably connected on opposite sides of an adjuster assembly 230 relative to a Y-direction, such that a rolling member 220 may roll along a first rolling portion 136 another rolling member 220 may roll along a second rolling portion 138.

With embodiments, such as generally illustrated in FIGS. 1A, 1B, and/or 6-11, a support member 200 may include an adjuster assembly 230 configured to facilitate adjustment of the position (e.g., in an X-direction) of a support member 200 relative to a track assembly 104. For example and without limitation, an electric motor 238 of the adjuster assembly 230 may rotate an adjuster pinion 250, which may engage the toothed portion 154 to adjust the position of the support member 200 relative to the track assembly 104, such as in an X-direction. An adjuster assembly 230 may be adjustably connected to a body of the support member 200 such that the adjuster assembly 230 may move and/or float relative to the body of the support member 200, such as in a Z-direction. Additionally and/or alternatively, an adjuster assembly 230 may be rotatable relative to the support member 200 and/or the track assembly 104, such as about an adjuster axis 240. An adjuster assembly 230 may be operatively connected to an electrical component of a support member 200, such as via one or more wires. For example and without limitation, an electrical component may provide power to and/or control operation of the electric motor 238.

With embodiments, such as generally illustrated in FIGS. 4A and 4B, an adjuster assembly 230 may include an adjuster body 232 and/or an adjuster member 234. An adjuster member 234 may generally extend from an adjuster body 232 in a Z-direction (e.g., downward in a Z-direction toward a mounting surface 106). An electrical motor 238 (see, e.g., FIG. 7) may be disposed at least partially in the adjuster body 232 and/or in the adjuster member 234. Additionally or alternatively, an electrical motor 238 may be disposed within a support assembly 102 and/or may be operatively connected to one or more support members 200. For example and without limitation, a support assembly 102 may include (i) two or more support members 200 disposed opposite one another (e.g., relative to a Y-direction) and/or (ii) an electrical motor 238 disposed between the two support members 200 and connected to an adjuster assembly 230 of one or both of the two support members 200, such as via a respective flex shaft, which may be curved and/or bent in some examples. In some circumstances, a transmission may connect an electrical motor 238 to an adjuster assembly 230.

With embodiments, such as generally illustrated in FIGS. 1B, 4B, and 9A-9C, an adjuster assembly 230 (e.g., an adjuster body 232 and/or an adjuster member 234) may include one or more portions (e.g., a tab 236) configured to contact and/or engage a slider 270 of a support member 200. For example and without limitation, a tab 236 may be configured as a protrusion extending from the adjuster body 232, such as generally in a Z-direction (e.g., downward in the Z-direction toward the mounting surface 106), and/or may be disposed offset from the adjuster member 234 relative to a Y-direction. Additionally and/or alternatively, a tab 236 may be configured as a surface, edge, slot, recess, body, and/or any other structure configured to engage a slider 270.

With embodiments, such as generally illustrated in FIGS. 1A, 4A, and 6-11, an adjuster assembly 230 (e.g., an adjuster body 232 and/or an adjuster member 234) may include one or more portions (e.g., a flange 242) configured to contact and/or engage an actuation body 330. An adjuster assembly 230 may be adjustable, such as in a generally Z-direction, via a flange 242. A flange 242 may extend generally in a Y-direction and/or may be disposed on an adjuster body 232, such as in a region of the adjuster body 232 opposite the adjuster member 234 relative to a Z-direction. A flange 242 may, additionally and/or alternatively, be disposed on the same or an opposite side of the adjuster assembly 230 relative to an adjuster pinion 250. Additionally and/or alternatively, a flange 242 may be configured as a surface, edge, slot, recess, body, and/or any other structure configured to engage an actuation body 330.

With embodiments, such as generally illustrated in FIGS. 4A, 4B, 6, 7, and 9A-11, an adjuster assembly 230 may include one or more portions (e.g., adjuster projections 244A, 244B) configured to contact and/or engage a support member 200. An adjuster projection 244A, 244B may extend from an adjuster body 232 (e.g., in a generally X-direction) and/or may facilitate rotation of an adjuster assembly 230 relative to a support member 200. An adjuster projection 244A, 244B may define and/or be disposed coaxially with an adjuster axis 240.

With embodiments, such as generally illustrated in FIGS. 4A, 4B, 6-8C, and/or 10A-11, a support member 200 may include an adjuster pinion 250. An adjuster pinion 250 may be configured to engage a toothed portion 154 of a track assembly 104. An adjuster pinion 250 may be rotatable about an adjuster pinion axis 252, which may extend generally in a Y-direction (e.g., perpendicular to a longitudinal direction of the track assembly 104). An adjuster pinion 250 may include one or more adjuster pinion teeth 254 configured to engage one or more track teeth 156 of a toothed portion 154. Adjuster pinion teeth 254 may extend radially outward from the adjuster pinion 250 relative to the adjuster pinion axis 252. An adjuster pinion 250 may be connected to an electric motor 238 directly and/or indirectly (e.g., via a flex shaft). For example and without limitation, an adjuster pinion 250 may be rotatably connected to an adjuster member 234, such as at a distal end of an adjuster member 234 that may be disposed opposite the adjuster body 232. An electric motor 238 may be operatively connected to an adjuster pinion 250 such that the adjuster pinion 250 is rotatable via the electric motor 238.

With embodiments, an adjuster pinion 250 (and the adjuster assembly 230, at least in some configurations) may be adjustable to a disengaged position (see, e.g., FIGS. 1B, 8A, 8B, 9A, 9B, 10A) in which the adjuster pinion 250 is disengaged from/not engaged with the toothed portion 154 (e.g., the adjuster pinion teeth 254 are not engaged with the track teeth 156) and/or an engaged position (see, e.g., FIGS. 1A, 8C, 9C, 10B) in which the adjuster pinion 250 is engaged with the toothed portion 154 (e.g., the adjuster pinion teeth 254 are engaged with the track teeth 156). A disengaged position may include, for example, an unaligned position (see, e.g., FIGS. 8A, 9A) in which the adjuster pinion 250 is disengaged from and not aligned with the toothed portion 154 (e.g., relative to a Z-direction) and/or an aligned position (see, e.g., FIGS. 1B, 8B, 9B, 10A) in which the adjuster pinion 250 is disengaged from and aligned with the toothed portion 154 (e.g., relative to a Z-direction). When in an unaligned position (see, e.g., FIGS. 8A, 9A), an adjuster pinion 250 and/or an adjuster assembly 230 (e.g., an adjuster member 234) may be disposed and/or extend obliquely or perpendicularly to a Z-direction. When in an aligned position (see, e.g., FIGS. 1B, 8B, 9B, 10A) and/or in an engaged position (see, e.g., FIGS. 1A, 8C, 9C, 10B), an adjuster pinion 250 and/or an adjuster assembly 230 (e.g., an adjuster member 234) may be disposed and/or extend generally parallel to a Z-direction. An adjuster pinion 250 and/or the adjuster assembly 230 may, for example, be adjusted generally downward in a Z-direction toward the disengaged position and/or may be adjusted generally upward in a Z-direction toward the engaged position. An adjuster pinion 250 and/or an adjuster assembly 230 may, when disengaged from the toothed portion 154 for example, be adjusted (e.g., moved, slid, rotated) generally laterally in a Y-direction toward an aligned position and/or toward an unaligned position.

With embodiments, an adjuster pinion 250 and/or an adjuster assembly 230, such as when in an unaligned position (see, e.g., FIGS. 8A, 9A), may be insertable into and/or removable from a track assembly 104, such as via being inserted into and/or removed from a track receptacle 130 through a track opening 128. When in an aligned position (see, e.g., FIGS. 1B, 8B, 9B, 10A), an adjuster pinion 250 and/or an adjuster assembly 230 may (i) restrict and/or prevent removal of the support member 200 from a track assembly 104 and/or (ii) facilitate adjustment of a support member 200 along a track assembly 104 (e.g., such as manual movement of a support assembly 102 by a user). When an adjuster pinion 250 and/or an adjuster assembly 230 is in the engaged position (see, e.g., FIGS. 1A, 8C, 9C, 10B), operation of an electric motor 238 may cause rotation of the adjuster pinion 250 about an adjuster pinion axis 252 and the adjuster pinion teeth 254 to engage the toothed portion 154 of the track assembly 104, which may cause movement of the support member 200 along the track assembly 104.

With embodiments, such as generally illustrated in FIGS. 1B, 5, and 8A-9C, a support member 200 may include a slider 270, which may be adjustable, movable, slidable, etc. in a direction generally parallel to an X-direction, for example. A slider 270 may be configured to engage and/or facilitate adjustment of the adjuster assembly 230 and/or an anchor 410, 450. Additionally and/or alternatively, a slider 270 may be configured to engage and/or facilitate adjustment (e.g., rotation) of an electrical connector 210 to engage one or more contacts 212 with a corresponding conductor 160. In examples, when a support assembly 102 is disposed on and/or connected to a track assembly 104, a slider 270 of the support assembly 102 and a toothed portion 154 of the track assembly 104 may be disposed on opposite sides of a track opening 128 relative to a Y-direction (e.g., a slider 270 may be disposed proximate/adjacent to a second track lip 134 and a toothed portion 154 may be disposed proximate/adjacent to a first track lip 132). A slider 270 may include one or more slider channels (e.g., a first slider channel 298A, a second slider channel 298B) configured to engage and/or adjust one or more anchors 410, 450 (e.g., via an anchor tab 418 of an associated anchor 410, 450).

With embodiments, such as generally illustrated in FIG. 11, a slider 270 may be disposed above an adjuster assembly 230 relative to a Z-direction. A tab 236 may extend from an adjuster assembly 230 generally upward in a Z-direction. A slider 270 may include a slider ramp portion 296 configured to engage a tab 236 of an adjuster assembly 230 to facilitate adjustment of the adjuster assembly toward an engaged position and/or a disengaged position. A slider ramp portion 296 may include a first section 296A configured to adjust/move an adjuster assembly 230 generally in a Z-direction and/or a second section 296B configured to adjust/move (e.g., rotate) an adjuster assembly 230 generally in a Y-direction toward an aligned position and/or an unaligned position. In examples, a first section 296A may extend generally in an X-direction in a sloped manner and/or a second section 296B may extend generally in a Y-direction in a sloped manner.

With embodiments, such as generally illustrated in FIG. 11, an adjuster assembly 230 and/or an adjuster pinion 250 may be disengaged from a track assembly 104 via adjusting a slider 270 (e.g., generally in an X-direction), which may cause a tab 236 to adjust, move, slide, etc. along the first section 296A of the ramp portion 296, which may cause the adjuster assembly 230 and/or the adjuster pinion 250 to disengage and/or move away from a toothed portion 154 of a track assembly 104 (e.g., generally downward in a Z-direction). In examples, adjusting a slider 270 (e.g., farther in the same X-direction) may cause a tab 236 to transfer from the first section 296A of the ramp portion 296 to a second section 296B and to then adjust, move, slide, etc. along the second section 296B, which may cause the adjuster assembly 230 and/or the adjuster pinion 250 to move out of Z-direction alignment with and/or away from a toothed portion 154 of a track assembly 104 (e.g., generally in a Y-direction). With embodiments, an adjuster assembly 230 and/or an adjuster pinion 250 may be adjusted into an aligned position and/or an engaged position via adjusting a slider 270 (e.g., in an opposite direction), which may involve the above described process being conducted in reverse.

In embodiments, such as generally illustrated in FIGS. 1B and 8A-9C, a slider 270 may be disposed between a top and bottom of the adjuster assembly 230. With embodiments, such as generally illustrated in FIGS. 1B, 5, and 9A-9C, a slider 270 may include a slider body 272, which may be configured as an elongated member and/or may extend generally in an X-direction. A slider 270 may include a slider protrusion 274, which may extend generally in a Z-direction. A slider protrusion 274 may be disposed on and/or connected to the slider body 272. A slider 270 and/or a slider protrusion 274 may include a guide surface 282 configured to engage, contact, and/or abut an adjuster assembly 230 (e.g., a tab 236). A guide surface 282 may extend generally in an X-direction and/or may face generally in a Y-direction. A guide surface 282 may include a first end 284, an intermediate section 286, and/or a second end 288. An intermediate section 286 may be offset from a first and/or second end 284, 288 (e.g., relative to a Y-direction) such that the guide surface 282 is sloped toward the intermediate section 286.

With embodiments, such as generally illustrated in FIGS. 9A-9C, when an adjuster pinion 250 and/or an adjuster assembly 230 is in an unaligned position (see, e.g., FIG. 9A), a tab 236 may be disposed adjacent to and/or in contact with a first end 284 of the guide surface 282 and/or may extend obliquely relative to a slider protrusion 274. An adjuster assembly 230 may, for example, be biased generally in a Y-direction (e.g., about an adjuster axis 240) such that a tab 236 is biased into contact with a slider protrusion 274 and/or a guide surface 282. When an adjuster pinion 250 and/or an adjuster assembly 230 is in an aligned position (see, e.g., FIG. 9B), a tab 236 may be disposed adjacent to and/or in contact with an intermediate section 286 of the guide surface 282 and/or may extend generally parallel to a slider protrusion 274. When an adjuster pinion 250 and/or an adjuster assembly 230 is in an engaged position, such as generally illustrated in FIG. 9C, a tab 236 may be disposed adjacent to and/or in contact with an intermediate section 286 of the guide surface 282, may extend generally parallel to a slider protrusion 274, and/or may be disposed spaced apart from a slider body 272 (e.g., generally in a Z-direction).

With embodiments, such as generally illustrated in FIGS. 1B, 5, and 9A-9C, a slider 270 may include one or more toothed slider portions 276 (e.g., gear racks) that may be configured to engage a slider pinion 280 of a support member 200, which may include one or more slider pinion teeth 294. A toothed slider portion 276 may include one or more slider teeth 278. A toothed slider portion 276 may generally extend in an X-direction. One or more (e.g., all) of the slider teeth 278 may be disposed one after another and/or aligned with one another in an X-direction. Slider teeth 278 may extend and/or protrude from a slider 270 and/or a toothed slider portion 276 generally in a Z-direction (e.g., upward in the Z-direction away the mounting surface 106).

With embodiments, such as generally illustrated in FIGS. 1B and/or 9A-9C, a support member 200 may include a slider pinion 280 configured to engage a toothed slider portion 276. A slider pinion 280 may include one or more slider pinion teeth 294 configured to engage one or more slider teeth 278. A slider pinion 280 may be rotatable about a slider pinion axis 290, that may extend generally in a Y-direction and/or that may be substantially coaxial with an engagement cam axis 314. A slider pinion 280 may be disposed on, connected to, and/or engaged with an engagement body 310 and/or an actuation shaft 292. A slider pinion 280 may be rotatable via rotating an actuation shaft 292, rotating an engagement body 310, and/or adjusting a slider 270 (e.g., generally in an X-direction). Additionally and/or alternatively, a slider pinion 280 may be configured to move independently of an actuation shaft 292 and/or an engagement body 310 (e.g., a slider pinion 280 may rotate without causing an actuation shaft 292 and/or an engagement body 310 to rotate, and/or the actuation shaft 292 may rotate without causing the slider pinion 280 to rotate). Rotating a slider pinion 280 may, at least in some situations, rotate an engagement body 310, such as with the slider pinion 280 and relative to the actuation shaft 292.

With embodiments, such as generally illustrated in FIGS. 1B and 9A-9C, a slider 270 may be actuated/moved in one or more of a variety of ways. For example, a slider 270 may be actuated via adjusting (e.g., rotating) a lever 214 of a support member 200, which may be engaged with and/or connected to the slider 270. A slider 270 may, for example, be actuated via an actuation shaft 292 and/or a slider pinion 280 connected thereto that may be engaged with a toothed slider portion 276 of the slider 270. Additionally or alternatively, a user may move a slider 270 directly and/or via a handle/lever/linkage.

With embodiments, such as generally illustrated in FIGS. 1A, 6, 10A, and 10B, a support member 200 may include an engagement body 310 that may be configured to facilitate adjustment of one or more anchors 410, 450 into and/or out of engagement with a toothed portion 154 of a track assembly 104. An engagement body 310 may be rotatable about an axis extending generally in a Y-direction (e.g., an engagement cam axis 314). An engagement body 310 may be operatively connected to one or more engagement member 350, 370 such that rotating the engagement body 310 adjusts the engagement members 350, 370 generally in an X-direction. An engagement body 310 may be disposed on, connected to, and/or engaged with an actuation shaft 292, an engagement cam 312, and/or a slider pinion 280. An engagement body 310 may be rotatable via rotating an engagement cam 312 (e.g., via rotating an actuation shaft 292) and/or rotating a slider pinion 280 (e.g., via adjusting a slider 270 with a lever 214). Additionally and/or alternatively, an engagement body 310 may be configured to, at least in some situations, rotate independently of an actuation shaft 292, an engagement cam 312, and/or a slider pinion 280. For example, rotation of the slider pinion 280 (e.g., via longitudinal movement of the slider 270) may cause rotation of the engagement body 310 relative to the actuation shaft 292 and/or the engagement cam 312, which may move the anchors 410, 450 without moving the adjuster assembly 230 (e.g., to maintain the adjuster assembly 230 in a disengaged position).

With embodiments, such as generally illustrated in FIGS. 1A, 6, 10A, and 10B, a support member 200 may include an engagement cam 312 that may be configured to facilitate adjustment of the adjuster assembly 230 and/or an adjuster pinion 250 into and/or out of engagement with a track assembly 104. An engagement cam 312 may be rotatable about an engagement cam axis 314, which may extend generally in a Y-direction. For example, an engagement cam 312 may be adjustable (e.g., rotatable) to a first position (see, e.g., FIG. 10A) and/or to a second position (see, e.g., FIG. 10B). An engagement cam 312 may include an engagement cam hub 316 and/or an engagement cam protrusion 318. An engagement cam protrusion 318 may extend radially from an engagement cam hub 316 relative to an engagement cam axis 314. An engagement cam 312 may be disposed on, connected to, and/or engaged with an actuation shaft 292 such that, for example, an engagement cam 312 is rotatable via rotating the actuation shaft 292. An engagement cam 312 may be connected to and/or engaged with an engagement body 310.

With embodiments, such as generally illustrated in FIGS. 1A and 1B, an engagement body 310, an engagement cam 312, and/or a slider pinion 280 may be rotatably connected to a support member 200 (and/or a second support member 200 disposed opposite the first support member 200). In examples, an engagement body 310, an engagement cam 312, and/or a slider pinion 280 may be connected to an actuation shaft 292 of a support member 200, which may be configured to rotate the engagement cam 312, the engagement body 310, and/or a slider pinion 280 about the engagement cam axis 314. For example and without limitation, an actuation shaft 292 may be configured to simultaneously engage and/or rotate a slider pinion 280 and/or an engagement cam 312. An actuation shaft 292 may be actuated manually and/or via a powered actuator (e.g., an electric motor), for example.

With embodiments, such as generally illustrated in FIGS. 1A, 10A, and 10B, a support member 200 may include an actuation body 330. An actuation body 330 may have and/or be rotatable about an actuation body axis 332, which may extend generally in a Y-direction. An actuation body 330 may include a first actuation portion 334 configured to engage, contact, and/or abut an adjuster assembly 230, such as a flange 242 for example. An actuation body 330 may include a second actuation portion 336 configured to engage, contact, and/or abut an engagement cam 312 (e.g., an engagement cam protrusion 318). An actuation body 330 may include a third actuation portion 338, which may engage and/or be connected to a biasing member 344 (e.g., a spring). A biasing member 344 may, additionally and/or alternatively, be connected to a body of a support member 200, such as at an end opposite the actuation body 330. A biasing member 344 may bias an actuation body 330 about an actuation body axis 332, which may bias a second actuation portion 336 into contact with an engagement cam 312 and/or may bias the first actuation portion 334 into contact with the adjuster assembly 230 (e.g., with the flange 242). The adjuster pinion 250 may be biased upward and into engagement with the toothed portion 154 and/or the track teeth 156, such as when the adjuster pinion 250 is in an engaged position. For example, biasing the first actuation portion 334 into contact with the adjuster assembly 230 (e.g., via the biasing member 344) may bias the adjuster assembly 230 upward, which may bias the adjuster pinion 250 upward and into engagement with the toothed portion 154 and/or the track teeth 156.

With embodiments, such as generally illustrated in FIGS. 1A, 6, 7, 10A, and/or 10B, a support member 200 may include one or more engagement members (e.g., a first engagement member 350, a second engagement member 370) configured to engage an anchor cam 430, 470. An engagement member 350, 370 may be an elongated member, which may extend generally in an X-direction. An engagement member 350, 370 may include an engagement member toothed portion 352, 372 (e.g., a gear rack), which may be configured to engage anchor cam teeth 438, 478 of an anchor cam 430, 470. An engagement member toothed portion 352, 372 may extend generally in an X-direction and/or may include one or more engagement member teeth 354, 374, which may be disposed one after another and/or aligned with one another in an X-direction. Engagement member teeth 354, 374 may extend and/or protrude from an engagement member 350, 370 and/or an engagement member toothed portion 352, 372 generally in a Z-direction (e.g., downward in the Z-direction toward the mounting surface 106). An engagement member 350, 370 may be operatively and/or adjustably connected to an engagement body 310, such as on an opposite side of the engagement body 310 from the engagement cam 312 for example. For example and without limitation, an engagement member 350, 370 may adjustably engage a slot or recess of the engagement body 310, which may be sloped toward an engagement cam axis 314, such that rotation of the engagement body 310 adjusts, moves, etc. the engagement member 350, 370 toward and/or away from the engagement cam axis 314. An engagement member 350, 370 may be operatively and/or adjustably connected to an anchor cam 430, 470. For example and without limitation, an engagement member 350, 370 may be adjusted, moved, slid, etc. generally in an X-direction via an engagement body 310, which may cause an engagement member toothed portion 352, 372 to engage and/or rotate an anchor cam 430, 470. A support member 200 is depicted in FIG. 6 without an actuation body 330 or a biasing member 344 to provide a clear view of the engagement body 310 and the engagement members 350, 370. A cross-sectional view through the engagement members 350, 370 of a support member 200 (e.g., in a plane perpendicular to a Y-direction) is generally depicted in FIG. 7 to provide a clear view of the engagement between the engagement members 350, 370 and the anchor cams 430, 470.

With embodiments, such as generally illustrated in FIGS. 1A, 6, 7, 10A, and/or 10B, a support member 200 may include one or more anchors (e.g., a first anchor 410, a second anchor 450) configured to engage and/or connect, secure, fix, etc. a support member 200 to a track assembly 104. An anchor 410, 450 may be adjustable generally in a Z-direction, may be adjustable generally in a Y-direction, and/or may be rotatable about an anchor axis 412, 452, which may extend generally in an X-direction. An anchor 410, 450 may include one or more toothed anchor portions 414, 454 (e.g., gear racks) configured to engage a toothed portion 154 of a track assembly 104 (see, e.g., FIGS. 6 and 7). A toothed anchor portion 414, 454 may include one or more anchor teeth 416, 456. A toothed anchor portion 414, 454 may extend generally in an X-direction. One or more (e.g., all) of the anchor teeth 416, 456 may be disposed one after another and/or aligned with one another in an X-direction. Anchor teeth 416, 456 may extend and/or protrude from an anchor 410, 450 and/or a toothed anchor portion 414, 454 generally in a Z-direction (e.g., upward in the Z-direction away the mounting surface 106). In examples, an anchor 410, 450 may be biased generally upward in a Z-direction (e.g., toward an engaged position), toward a toothed portion 154 generally in a Y-direction, and/or about an anchor axis 412, 452 such as via an anchor biasing member 426, 466. An anchor biasing member 426, 466 (e.g., a spring) may be connected to, disposed on, and/or engaged with a portion of a support member 200 (e.g., a body of the support member 200) and/or a portion of an anchor 410, 450.

With embodiments, such as generally illustrated in FIGS. 12A-13B, an anchor 410 may include an anchor tab 418 that may be configured to engage a slider 270 (e.g., via being at least partially received in a slider channel 298A).

An anchor tab 418, an anchor adjustment portion 444, and/or a tilt protrusion 448 may extend from an anchor 410 generally perpendicularly to the anchor 410 and/or may be disposed adjacent/proximate an anchor opening 446. Additionally or alternatively, an anchor adjustment portion 444 and/or a tilt protrusion 448 may be configured as a surface, edge, body, and/or other structure configured to engage an anchor cam projection 440 and/or an anchor cam protrusion 436. While the above description and FIGS. 12A-13B describe/show a first anchor 410 including an anchor tab 418, an anchor adjustment portion 444, an anchor opening 446, and/or a tilt protrusion 448, a second anchor 450 may (or may not) include an anchor tab, an anchor adjustment portion, an anchor opening, and/or a tilt protrusion which may be configured in the same or similar manner as corresponding features of a first anchor 410.

With embodiments, such as generally illustrated in FIGS. 6, 7, 10A, 10B, 13A, and/or 13B, an anchor 410, 450 may include a ramp portion (e.g., a first anchor ramp portion 420, a second anchor ramp portion 460) configured to engage an anchor cam 430, 470. A ramp portion 420, 460 may project from an anchor 410, 450 generally in a Y-direction. A ramp portion 420, 460 may extend along an anchor 410, 450, such as from a first ramp end 422, 462 to a second ramp end 424, 464, in a curved manner. A first ramp end 422, 462 may be disposed above a second ramp end 424, 464 relative to a Z-direction, and/or a second ramp end 424, 464 may project farther from an anchor 410, 450 generally in a Y-direction than a first ramp end 422, 462, such that the ramp portion 420, 460 is sloped generally downward in a Z-direction and away from the anchor 410, 450 generally in a Y-direction.

With embodiments, such as generally illustrated in FIGS. 1A, 6, 7, 10A, 10B and/or 12A-13B, a support member 200 may include an anchor cam (e.g., a first anchor cam 430, a second anchor cam 470), which may be configured to engage and/or facilitate adjustment of an anchor 410, 450. An anchor cam 430, 470 may be rotatable about an anchor cam axis 432, 472, which may extend generally in a Y-direction. An anchor cam 430, 470 may include an anchor cam hub 434, 474 and/or an anchor cam protrusion 436, 476. An anchor cam protrusion 436, 476 may extend radially from an anchor cam hub 434, 474 relative to an anchor cam axis 432, 472. An anchor cam protrusion 436, 476 may be configured to contact, abut, and/or engage a ramp portion 420, 460 of an anchor 410, 450. An anchor cam 430, 470 may include on or more anchor cam teeth 438, 478, which may extend radially relative to an anchor cam axis 432, 472, via which an anchor cam 430, 470 may engage an engagement member toothed portion 352, 372 of an engagement member 350, 370. An anchor cam 430, 470 may be rotatably connected to a support member 200 and/or an anchor 410, 450. In examples, an anchor cam 430, 470 may be connected to an engagement member toothed portion 352, 372 of an engagement member 350, 370, which may be configured to rotate the anchor cam 430, 470 about an anchor cam axis 432, 472.

With embodiments, such as generally illustrated in FIGS. 12A and 12B, an anchor cam 430 may include an anchor cam projection 440, which may be connected to and/or extend radially from an anchor cam base 442. An anchor cam projection 440 may be configured to contact, abut, and/or engage an anchor adjustment portion 444 of a corresponding anchor 410. An anchor cam base 442 may extend at least partially through an anchor opening 446 of an anchor 410 (e.g., generally in a Y-direction and/or perpendicular to the anchor 410). An anchor cam protrusion 436 and an anchor cam projection 440 may be disposed at and/or connected to opposite ends of an anchor cam base 442 such that, for example, the anchor cam protrusion 436 and the anchor cam projection 440 may be disposed on opposite sides of an anchor 410. An anchor cam 430 may be configured such that, when disengaging an anchor 410 from a track assembly 104, an anchor cam projection 440 may adjust an anchor 410 generally downward in a Z-direction to disengage the anchor 410 from a toothed portion 154 of the track assembly 104 (e.g., via engaging an anchor adjustment portion 444), such as prior to an anchor cam protrusion 436 adjusting the anchor 410 away from the toothed portion 154 generally in a Y-direction (e.g., via engaging a ramp portion 420), at least to some degree. Additionally or alternatively, an anchor cam 430 may be configured such that, when engaging an anchor 410 with a track assembly 104, an anchor cam protrusion 436 may adjust and/or allow adjustment of the anchor 410 toward a toothed portion 154 of the track assembly 104 generally in a Y-direction (e.g., via disengaging a ramp portion 420 and/or via an anchor biasing member 426 applying a biasing force), such as prior to an anchor cam projection 440 adjusting and/or allowing adjustment of an anchor 410 generally upward in a Z-direction to engage the anchor 410 with the toothed portion 154 (e.g., via disengaging an anchor adjustment portion 444 and/or an anchor biasing member 426 applying a biasing force). While the above description and FIGS. 12A and 12B describe/show a first anchor cam 430 including an anchor cam projection 440 and/or an anchor cam base 442, a second anchor cam 470 may (or may not) include an anchor cam projection and/or an anchor cam base which may be configured in the same or similar manner as corresponding features of a first anchor cam 430.

With embodiments, an adjuster assembly 230 may be engaged with a track assembly 104 (e.g., in an engaged position) when an anchor 410, 450 is disengaged from a track assembly 104 (see, e.g., FIG. 10B) such that the support member 200 is connected/secured to the track assembly 104 and/or is adjustable along the track assembly 104 such as via operation of an electric motor 238. Additionally and/or alternatively, an adjuster assembly 230 may be disengaged from and/or out of Z-direction alignment with a track assembly 104 (e.g., in an unaligned position) when an anchor 410, 450 is out of Z-direction alignment with a track assembly 104 such that the support member 200 is removable from and/or insertable into a track assembly 104 in a plurality of locations along the track assembly 104. An adjuster assembly 230 may be disengaged from a track assembly 104 (e.g., in an aligned and/or unaligned position) when an anchor 410, 450 is engaged with a track assembly 104 (see, e.g., FIG. 10A), which may protect the adjuster assembly 230 (e.g., an adjuster pinion 250) from damage (at least to some degree) in the event of a collision and/or an application of abnormal stress (e.g., stress exceeding that which occurs during normal use and/or operation) to the support assembly 102 and/or the track assembly 104. With embodiments, an adjuster assembly 230 and/or an adjuster pinion 250 may default to an aligned position and/or an anchor 410, 450 may default to an engaged position.

With embodiments, such as generally illustrated in FIG. 10B, when an engagement cam 312 is in a second engagement cam position, an adjuster assembly 230 and/or an adjuster pinion 250 may be engaged with a track assembly 104, and/or removal of a support member 200 from a track assembly 104 may be restricted and/or prevented via the adjuster assembly 230 (e.g., depending on the position of the adjuster assembly 230), and/or a support member 200 may be adjustable relative to the track assembly 104, such as by actuating a motor 238 of the adjuster assembly 230 and/or rotating the adjuster pinion 250. In a second engagement cam position, (a) a second actuation portion 336 may be spaced apart (e.g., radially) from an engagement cam hub 316 and/or an engagement cam protrusion 318, (b) a first actuation portion 334 may engage, contact, and/or press against an adjuster assembly 230 (e.g., a flange 242) such as generally in a Z-direction, (c) an anchor cam 430, 470 may be oriented such that (i) an anchor cam projection 440 engages and/or contacts an anchor adjustment portion 444 (see, e.g., FIG. 12B) and/or (ii) an anchor cam protrusion 436, 476 engages and/or contacts a ramp portion 420, 460 (see, e.g., FIG. 13B), (d) an anchor 410, 450 may be disengaged from a toothed portion 154 of a track assembly 104 (e.g., disposed in a disengaged position), and/or (e) an adjuster assembly 230 and/or an adjuster pinion 250 may be engaged with a toothed portion 154 of a track assembly 104 (e.g., disposed in an engaged position). Additionally and/or alternatively, a second actuation portion 336 may contact and/or be biased against an engagement cam hub 316 when an engagement cam 312 is in a second engagement cam position.

With embodiments, such as generally illustrated in FIGS. 8A-10B, engaging and/or connecting a support assembly 102 on a track assembly 104 may include inserting (e.g., moving sliding, rotating, etc.) an adjuster pinion 250, an adjuster assembly 230, and/or one or more anchors 410, 450 into a track receptacle 130 and adjusting an adjuster pinion 250, an adjuster assembly 230, and/or one or more anchors 410, 450 generally in a Y-direction into Z-direction alignment with a toothed portion 154 of a track assembly 104 (e.g., from an unaligned position toward an aligned position), which may include rotating the adjuster assembly 230 and/or the adjuster pinion 250 (e.g., about an adjuster axis 240) and/or an anchor 410, 450 (e.g., about an anchor axis 412, 452), such as by rotating an anchor cam 430, 470 and/or by adjusting, sliding, moving, etc. the adjuster assembly 230, an anchor 410, 450, and/or a slider 270 for example. Engaging and/or connecting a support assembly 102 on a track assembly 104 may include adjusting an adjuster assembly 230, an adjuster pinion 250, and/or an anchor 410, 450 into engagement with a toothed portion 154 of a track assembly 104 (e.g., from an aligned position toward an engaged position), such as by adjusting (e.g., moving sliding, rotating, etc.) an adjuster assembly 230, an adjuster pinion 250, and/or an anchor 410, 450 generally upward in a Z-direction, which may include adjusting (e.g., rotating, sliding, etc.) an actuation body 330, an engagement cam 312, an engagement body 310, an actuation shaft 292, and/or a slider 270. Disengaging and/or disconnecting a support assembly 102 and a track assembly 104 may include adjusting (e.g., moving sliding, rotating, etc.) an adjuster assembly 230, an adjuster pinion 250, and/or an anchor 410, 450, in an opposite direction for example, which may involve the above described process being conducted in reverse.

With embodiments, an adjuster assembly 230 and/or an adjuster pinion 250 may be (i) adjusted to an aligned position and/or an unaligned position via actuating a lever 214, and/or (ii) adjusted to an engaged position and/or an aligned position via rotating an actuation shaft 292. In embodiments, an anchor 410, 450 may be adjusted to an engaged position, an aligned position, and/or an unaligned position via actuating a lever 214 and/or rotating an actuation shaft 292. Rotation of an actuation shaft 292 may, in some circumstances, be restricted and/or prevented when the adjuster assembly 230 and/or adjuster pinion 250 is in an unaligned position (e.g., is not in an aligned position or an engaged position). Additionally and/or alternatively, actuation of a lever 214 may, in some circumstances, be restricted and/or prevented when an adjuster assembly 230 and/or adjuster pinion 250 is engaged with a toothed portion 154 (e.g., is not in an aligned position or an unaligned position).

With embodiments, actuating (e.g., adjusting, rotating, etc.) a lever 214 of a support member 200 may cause the lever 214 to contact and/or press against a slider 270, which may cause the slider 270 to slide, shift, move, etc. (e.g., generally in an X-direction) relative to an adjuster assembly 230 and/or an anchor 410, 450 which may cause a toothed slider portion 276 of the slider 270 to engage a slider pinion 280 (e.g., via slider pinion teeth 294 and slider teeth 278), which may cause the slider pinion 280 to rotate about an axis (e.g., an engagement cam axis 314). Rotation of the slider pinion 280 (i) may not cause an actuation shaft 292 to rotate such that an engagement cam 312 is not adjusted and does not adjust the adjuster assembly 230, and/or (ii) may cause an engagement body 310 to rotate, which may adjust an anchor 410, 450 to an engaged position, an aligned position, and/or an unaligned position. Adjusting a slider 270 via an actuating a lever 214 may, additionally and/or alternatively, cause the slider 270 to (i) engage a tab 236 of an adjuster assembly 230, which may adjust an adjuster assembly 230 and/or an adjuster pinion 250 to an aligned position and/or an unaligned position, and/or (ii) engage an anchor tab 418, which may adjust and/or facilitate adjustment of an anchor 410 to an engaged position, an aligned position, and/or an unaligned position. For example and without limitation, a slider channel 298A of a slider 270 may engage an anchor tab 418 to adjust and/or guide an anchor 410 from an unaligned position to an aligned position and/or from an aligned position to an engaged position, which may supplement an anchor biasing member 426 that may (e.g., simultaneously) adjust/bias the anchor 410 (e.g., via providing a biasing force that biases the anchor 410 toward the engaged position).

With embodiments, rotating an actuation shaft 292 may rotate an engagement cam 312, which may adjust an adjuster assembly 230 and/or an adjuster pinion 250 to an engaged position and/or an aligned position. Additionally and/or alternatively, rotating an actuation shaft 292 may rotate an engagement body 310 (e.g., via rotating the engagement cam 312), which (i) may not cause a slider pinion 280 to rotate such that movement of a slider 270 is not caused by rotation of the actuation shaft 292, and/or (ii) may adjust an engagement member 350, 370 and/or an anchor cam 430, 470 to adjust an anchor 410, 450 to an engaged position, an aligned position, and/or an unaligned position.

For example and without limitation, upon insertion of a support assembly 102 into a track assembly 104, the anchors 410, 450, an adjuster assembly 230, and/or an adjuster pinion 250 may be disposed in or proximate to unaligned positions, such as to facilitate insertion/connection. Then, a lever 214 may be actuated (e.g., by a user, an actuator, and/or a biasing mechanism) to adjust a slider 270, which may (i) adjust an adjuster assembly 230 and/or an adjuster pinion 250 from an unaligned position to an aligned position (e.g., via engaging a tab 236) and/or (ii) adjust an anchor 410, 450 from an unaligned position and/or an aligned position to an engaged position (e.g., via an anchor biasing member 426, 466, engaging an anchor tab 418, and/or rotating a slider pinion 280 to rotate an engagement body 310 without rotating the actuation shaft 292). Subsequently, an actuation shaft 292 may be rotated, which may (i) adjust an adjuster assembly 230 and/or an adjuster pinion 250 from an aligned position to an engaged position (e.g. via rotating an engagement cam 312) and/or (ii) adjust an anchor 410, 450 from an engaged position to an aligned position and/or unaligned position (e.g., via rotating the engagement cam 312 to rotate an engagement body 310 without rotating the slider pinion 280), which may unlock the support assembly 102 from the track assembly 104 to facilitate movement of the support assembly 102 via the adjuster assembly 230 along the track assembly 104. An actuation shaft 292 may be rotated in an opposite direction or a lever 214 actuated in an opposite direction, for example, to reengage an anchor 410, 450 with a track assembly 104 and/or to disengage an adjuster assembly 230 and/or an adjuster pinion 250 from a track assembly 104, which may involve one or more portions of the above described process being conducted in reverse.

With embodiments, such as generally illustrated in FIGS. 8A, 8B, 9A, and 9B, adjusting an adjuster pinion 250 and/or an adjuster assembly 230 toward an aligned position (see, e.g., FIGS. 8B and 9B) and/or an unaligned position (see, e.g., FIGS. 8A and 9A) may include rotating the adjuster pinion 250 and/or the adjuster assembly 230 about an adjuster axis 240, such as by adjusting, sliding, moving, etc. the adjuster assembly 230 and/or a slider 270. A slider 270 and/or an adjuster assembly 230 may be adjusted, moved, slid, etc. (e.g., generally in the X-direction), which may cause a tab 236 to engage and/or slide along the guide surface 282, which may cause the adjuster assembly 230 and/or an adjuster pinion 250 to adjust (e.g., rotate) toward an aligned position and/or an unaligned position. Adjusting a slider 270 and/or an adjuster assembly 230 to adjust an adjuster pinion 250 into Z-direction alignment with a toothed portion 154 of a track assembly 104 (e.g., from an unaligned position to an aligned position) may include actuating a lever 214, which may cause the slider 270 to slide, shift, move, etc. relative to the adjuster assembly 230 (e.g., generally in an X-direction), which may cause a tab 236 to slide along a guide surface 282 toward an intermediate section 286 (e.g., from a first end 284), which may cause the adjuster assembly 230 to rotate about an adjuster axis 240, which may adjust the adjuster pinion 250 generally in a Y-direction (e.g., away from the slider 270) toward the aligned position (see, e.g., FIGS. 8B and 9B). The slider 270 and/or the adjuster assembly 230 may be adjusted/moved, in an opposite direction for example, to adjust the adjuster assembly 230 and/or an adjuster pinion 250 toward an unaligned position (see, e.g., FIGS. 8A and 9A), such as from an aligned position (see, e.g., FIGS. 8B and 9B), which may involve the above described process being conducted in reverse.

With embodiments, such as generally illustrated in FIGS. 8C, 9C, 10A, and 10B, adjusting an adjuster pinion 250 and/or an adjuster assembly 230 toward an engaged position (see, e.g., FIGS. 1A, 8C, 9C, 10B) and/or a disengaged position, such as an aligned position (see, e.g., FIGS. 1B, 8B, 9B, 10A), may include adjusting an adjuster assembly 230 generally in a Z-direction, such as by rotating an actuation shaft 292 and/or an engagement cam 312. Adjusting (e.g., rotating) an engagement cam 312 may cause an actuation body 330 to rotate about an actuation body axis 332, which may cause the actuation body 330 to adjust, move, push, etc. an adjuster assembly 230 generally in a Z-direction, which may cause the adjuster assembly 230 and/or an adjuster pinion 250 to adjust toward an engaged position and/or a disengaged position (e.g., an aligned position). Adjusting (e.g., rotating) an engagement cam 312 about an engagement cam axis 314 may, additionally, alternatively, and/or simultaneously, rotate an engagement body 310, which may cause an engagement member 350, 370 to adjust, move, slide, etc. generally in an X-direction, which may cause an anchor cam 430, 470 to adjust (e.g., rotate about an anchor cam axis 432, 472), which may cause an anchor 410, 450 to engage and/or disengage a toothed portion 154 of a track assembly 104, which may (e.g., temporarily) fix the support member 200 and the track assembly 104 to one another. By configuring an actuation shaft 292 to simultaneously rotate an engagement body 310 and/or an engagement cam 312 for example, an adjuster assembly 230 may be engaged with a track assembly 104 and/or one or more anchors 410, 450 may be disengaged from a track assembly 104 (or vice versa) by a single action (e.g., rotating an actuation shaft 292), which may facilitate adjustment of a support assembly 102 relative to a track assembly 104.

With embodiments, such as generally illustrated in FIGS. 8C, 9C, 10A, and 10B, when adjusting an engagement cam 312 to adjust an adjuster assembly 230 and/or an adjuster pinion 250 toward an engaged position (see, e.g., FIGS. 1A, 8C, 9C, 10B), for example from a disengaged and/or an aligned position (see, e.g., FIGS. 1B, 8B, 9B, 10A), an engagement cam 312 may be rotated (e.g., counter-clockwise) about an engagement cam axis 314, such as via rotating an actuation shaft 292, which may cause a second actuation portion 336 engaging an engagement cam protrusion 318 to adjust, move, slide, off of the engagement cam protrusion 318 (e.g., to a position in which the second actuation portion 336 is disposed spaced slightly apart from and/or in contact with an engagement cam hub 316), which may cause the actuation body 330 to rotate (e.g., clockwise) about an actuation body axis 332, which may cause a first actuation portion 334 to move and/or adjust generally upward in a Z-direction such that it adjusts, presses, pushes, etc. a flange 242 of an adjuster assembly 230 generally upward in a Z-direction, which may cause the adjuster assembly 230 and/or an adjuster pinion 250 to move generally upward in a Z-direction to engage a toothed portion 154 of a track assembly 104. An actuation shaft 292 and/or an engagement cam 312 may be adjusted, moved, rotated, etc., in an opposite direction for example, to adjust (i) the adjuster assembly 230 and/or an adjuster pinion 250 toward a disengaged position (see, e.g., FIGS. 8B, 9B, 10A) such as from an engaged position (see, e.g., FIGS. 8C, 9C, 10B).

With embodiments, such as generally illustrated in FIGS. 10A and 10B, engaging and/or disengaging an anchor 410, 450 from a toothed portion 154 of a track assembly 104 may, additionally and/or alternatively, include adjusting (e.g., rotating) an engagement body 310 about an axis extending generally in a Y-direction (e.g., an engagement cam axis 314). An engagement body 310 may be rotated to engage and/or disengage an anchor 410, 450 from a track assembly 104 via actuating a lever 214 (e.g., when adjusting an adjuster assembly 230 and/or adjuster pinion 250 between an aligned position and an unaligned position) and/or via rotating an actuation shaft 292 (e.g., when adjusting an adjuster assembly 230 and/or adjuster pinion 250 between an engaged position and an aligned position).

For example and without limitation, disengaging an anchor 410, 450 from a toothed portion 154 of a track assembly 104 (e.g., adjusting an anchor 410, 450 from the position of FIGS. 10A, 12A, 13A toward the position of FIGS. 10B, 12B, 13B) may include rotating an engagement body 310 about an axis extending generally in a Y-direction (e.g., an engagement cam axis 314), such as via actuating a lever 214 (e.g., when adjusting an adjuster assembly 230 from an aligned position to an unaligned position) and/or via rotating an actuation shaft 292 (e.g., when adjusting an adjuster assembly 230 from an aligned position to an engaged position), which may adjust, move, slide, etc. an engagement member 350, 370 generally in an X-direction away from the engagement body 310 (e.g., via adjusting an engagement member 350, 370 within a slot or groove of the engagement body 310), which may cause an engagement member toothed portion 352, 372 to engage, contact, etc. one or more anchor cam teeth 438, 478, which may cause an anchor cam 430, 470 to rotate about an anchor cam axis 432, 472, which may adjust an anchor cam projection 440 (e.g., from the position of FIG. 12A toward the position of FIG. 12B) to engage, contact, and/or press against an anchor adjustment portion 444 (e.g., opposite a biasing force applied to an anchor 410, 450 by an anchor biasing member 426, 466), which may adjust and/or move an anchor 410, 450 generally downward in a Z-direction, which may cause a toothed anchor portion 414, 454 to disengage a toothed portion 154 of a track assembly 104.

With embodiments, rotating an anchor cam 430, 470 about an anchor cam axis 432, 472 may, additionally, alternatively, and/or simultaneously, cause an anchor cam protrusion 436, 476 to slide along a ramp portion 420, 460 generally downward in a Z-direction toward a second ramp end 424, 464 such as from a first ramp end 422, 462 (e.g., from the position of FIG. 13A toward the position of FIG. 13B, and/or opposite a biasing force applied to an anchor 410, 450 by an anchor biasing member 426, 466), which may adjust and/or move an anchor 410, 450 generally/substantially in a Y-direction (e.g., via rotating about an anchor axis 412, 452), which may cause a toothed anchor portion 414, 454 to move away from and/or out of Z-direction alignment with a toothed portion 154 of a track assembly 104. An engagement body 310 may be adjusted, moved, rotated, etc., in an opposite direction for example, to adjust an anchor 410, 450 into engagement with a toothed portion 154 of a track assembly 104, which may involve the above described process being conducted in reverse.

With embodiments, a method of operating a track system 100 may include providing a track assembly 104 and one or more support assemblies 102. The support assembly 102 and/or a support member 200 may be disposed on and/or connected with a track assembly 104, such as by inserting the support member 200 into the track assembly 104 a vertical direction (e.g., a Z-direction). At least a portion of an adjuster assembly 230 (e.g., an adjuster pinion 250) of a support member 200 of the support assembly 102 may be adjusted/moved (e.g., rotated), such as from an unaligned position, into alignment with a toothed portion 154 of the track assembly 104 such that the adjuster assembly 230 and/or the adjuster pinion 250 is disposed in an aligned position. Adjusting an adjuster assembly 230 and/or an adjuster pinion 250 from an unaligned position to an aligned position may include rotating the adjuster pinion 250 and/or the adjuster assembly 230 about an adjuster axis 240, such as by adjusting, sliding, moving, etc. the adjuster assembly 230 and/or a slider 270 for example. Adjusting an adjuster pinion 250 and/or an adjuster assembly 230 toward an engaged position, from an aligned position for example, may include adjusting (e.g., moving sliding, rotating, etc.) an adjuster pinion 250 and/or an adjuster assembly 230 generally upward in a Z-direction toward the engaged position to engage the adjuster pinion 250 and the toothed portion 154 of the track assembly 104, such as by adjusting (e.g., rotating) an actuation shaft 292, an engagement cam 312, an actuation body 330, and/or an engagement body 310. When in the engaged position, the adjuster assembly 230 and/or an electric motor 238 thereof may be actuated such that the adjuster pinion 250 rotates, which may move the support assembly 102 along and/or relative to the track assembly 104 to adjust a longitudinal position of the support member 200. An electrical component of the support assembly 102 may, for example, control operation of the electric motor 238. Disengaging the adjuster assembly 230 and/or the adjuster pinion 250 from the toothed portion 154 may facilitate removal of the support assembly 102 and/or may mitigate damage to the adjuster assembly 230 in the event of a vehicle collision. Disengaging and/or disconnecting a support assembly 102 and a track assembly 104 may include adjusting (e.g., moving, sliding, rotating, etc.) an adjuster pinion 250 and/or an adjuster assembly 230, in an opposite direction for example, which may involve the above described process being conducted in reverse.

While embodiments of a track system 100 are generally described in connection with a support assembly 102 connected with a track assembly 104, multiple support assemblies 102, which may include one or a plurality of support members 200, may be connected to the same track assembly 104, which may include one or a plurality of pairs of tracks 120, 150 (e.g., for a plurality of seats in a vehicle 108).
